GLARE SHIELD FOR HEADLIGHTS.

Application filed. March 3-1, 1923. feerlal No. 629,107.

To all whom it may concern:

Be it known that we, CHARLES H. HIPP and SHERMAN L. Kisnn. citizens ofthe United States, and residents, respectively, of *Camp Lewis,Washington, and Hutchmson, in the county of Reno and State of Kansas,have invented a new and Improved Glare Shield for Headlights, of whichthe followin is a full, clear, and exact description.

his invention has relation to headlights formotor vehicles and hasparticular reference to an attachment therefor to eliminate the blindingglare in the eyes of pedestrians or drivers of approaching vehicles.

Une of the principal objects of the present invention is to provide anattachment of the character described which serves to eliminate theglare and at the same time in no way impairs the light of the roadway inadvance of the vehicle.

As a further object the provide a glare shield for headlights which maybe readily attached to the ordinary forms of headlights now in generaluse without materially altering the construction of the same.

The invention further contemplates an attachment for vehicle headlightswhich in addition to serving as a glare shield will function to increasethe vision of the driver of a vehicle in a fog or rain.

As a still further object the invention aims to provide a device of thecharacter set forth which is extremely simple in coninvention aims tostruction, inexpensive to manufacture and which is thoroughly reliableand highly efficient in its purpose.

With the above recited and other objects in View, the invention residesin the novel construction set forth in the following specification,particularly pointed out in the appended claims and illustrated in theaccompanying drawing, it being understood that the right is reserved toembodiments other than those actually illustrated herein to the fullextent indicated by the general meaning of the terms in which the claimsare expressed.

In the drawing- Figure 1 is a sectional view through a headlight andglare shield constructed in accordance with the invention.

a fragmentary longitudinal Fig. 2 is a front view thereof, arts beingbroken away to disclose the un erlymg structure.

Fig. 3 is a plan view of the glare shield removed.

Referring to the drawing by characters of reference A designates theouter shell or casing of a headlight of standard construction and B theinner parabolic reflecting shell which is designed to normally diffusethe light rays from the lamp C therefrom to spread the same and castreflections at various angles from said reflecting surface. The glareshield which constitutes the invention consists of a cylindricalsupporting member formed at its opposite ends with inwardly projectingannular flanges 11 and outwardly projecting annular flanges 12. Theflanges 11 are provided with vertically spaced notches 13 in the opposedside edges thereof to receive a plurality of vertically spaced vanes 14.The rear ends-of the vanes 14 have their rear corners cut away as at 15whereby when the glare shield is supported in axial prolongation fromthe headlight, the cutaway portions of the rear ends of the vanescompensating for the curvature of the inner reflecting shell B so as notto contact therewith. In the standard forms of headlights the door whichcarries the lens is not of sufficient length to allow for theinstallation of the glare shield, and for this reason a substitute doorfor containing the glare shield will be furnished or provided with theglare shield. As illustrated in the drawing the substitute door willconsist of a cylindrical section 16 of a diameter to snugly receive theouter flanges 12. An annular section constituting an inwardly curvedhead 17 is threadedly engaged over the outer end of the cylindricalsection 16 against which the lens 18 will engage. The lens will bemaintained against the annular section or head 17 by the outer end ofthe glare shield, the outer flange 12 of which is provided with anannular groove 19 in which a gasket 20 is seated to impinge against theinner face of the lens. The other outer flange 12 is likewise providedwith an annular gasket seat 21 in which a gasket 22 is arranged to seatagainst the outturned portion 23 of the reflecting shell when the innerend of the cylindrical section of the door 16 is engaged over the doorseat 24.

' When installed on the lamp, the lamp and glare shield are tilteddownwardly at approximately 3, three degree angle so that it will beimpossible for the glare to be seen above the level of the lampregardless of how far the observer is away from the same. Thearrangement of the glare shield permits only parallel light rays to beprojected through thevanes or deflectors 14 thereby cutting off allvertical angular rays or reflections while ermitting a straight or axialreflection and ateral angular reflections to be cast from the headlight.It will thus be seen that a slight downward tilting will shield from theeyes of an observer all reflection or glare from the reflecting elementof the headlight, without in any way detracting from the illumination ofthe road in advance of the vehicle.

We claim:

1. In a glare shield for headlights, means associated with saidheadlight for eliminating the casting of vertical angular reflectionswhile permitting of the castin of horizontal angular reflections andaxia reflections, said means comprising a plurality of vertically spacedhorizontal vanes projecting forwardly and disposed immediately inadvance of the headlight reflecting element, and a support for saidvanes consisting of a cylindrical body having inwardly projectingannular flanges at its opposite ends, said flanges formed with alignednotches receiving the side edges of said vanes.

2. A glare shield of the'character described comprising a cylindricalbody having outwardly and inwardly projecting annular flanges at itsopposite ends and of a diameter approximately equal to the diameter ofthe reflecting element of a headlight, horizontal aligned notches in theinner flanges, and a plurality of vanes having their side edgesrespectively engaged in the aligned notches of the inner flanges.

3. A glare shield of the character described comprising a cylindricalbody having outwardly and inwardly projecting annular flanges at itsopposite ends and of a diameter approximately equal to the diameter ofthe reflecting element of a headlight, horizontal aligned notches in theinner flanges, a plurality of vanes having their side edges respectivelyengaged in the aligned notches ,of the inner flanges, and meansforassociating said glare shield with the headlight comprising acylindrical member having an inwardly projecting annular head at itsouter end and a transparent lens within which member the outward- 1yprojecting flanges of the supporting body are snugly received, saidsupportin member telescopically engaging over t e forward end of theheadlight.
